Another test, without a reinstall of AS16&ASCA, showed the tower has the active weather info, when asking for takeoff. He will give wind data with permission for takeoff. The data is correct. I think I don´t need to reinstall AS16&ASCA...
Thanks for letting us know. Again, it's possible there is a delay in loading the weather data but it does sound like the data is being loaded eventually.
A short offtopic question: Is there only ATC chatter for the AI, or also random chatters
There is no random or canned chatter in PF3. All chatter depends on AI activity as well as the specific frequency or facility. For example, if you are tuned to Tower, you will only hear AI that are tuned to Tower, not AI tuned to Departure or Center.
